paratus for Liquid-Hydrocarbon Burners, of

z ployedfor sup lyin 4ing liquid hy rocar [l which the followingis a specification, reference being had therein to the accompanying drawings. 'l f 1 The invention consists ingeneral in improvements .in .the a paratus which is emon-esuch, for instance, as thosewhich are used in connection with self-propelled ,or motor vehiclesand the like.

T e invention has been designed with its use in combination with'the burners of selfpropelled or motor vehicles in mind but it will be clear that it is not limited to this precise use and that itmay be' employed elsewhere as well. In the drawings for convenience I have re resented the same asv employed u on a sel -propelled or motor vehicle, and. IP will thus describe the same. l f

The invention consists in an auxiliary system which-isL combined with the main or usual gasolene system, as hereinafter eX- plained, and a by-pass by means of which the two systems are relieved in case of accident such as will be described. A

In the drawings, Fi re 1 is a view on the order of a diagram, il ustratin the various features of the invention and t e manner of reducing the invention to ractice, certain parts being in elevation an i others in vertical'section. Fig. 2 is a-viewshowing the force-pump and the means of o erating the same. Fig. 3 is a view of the reief-device in central vertical section. 'Y

Having reference to the-drawin`s,-at 2 Fig. 1, is intended tobe represente a boiler' of any of the kinds commonly in use on vehicles such as have been referred to, andv at 3 is `employed in lconnection Vwith ythe vsaid boiler.v Only theeXteriors of the` boiler and burner are represented since the said parts may be of any usual or suitable character and construction.

4 designates a pipe through which the liqel to burnersconsummore especiallyl pump, alsojcoinbined wit the said uid -hydrocarbon fuel, hereinafter termed gasolene', inasmuch as gasolene is the substance most .commonly in use at the present time, iinds its way to the burner 3. The usual holder or container for asolene is intended to be indicated'at 5,l tie said pipe 4 being in communication therewith, as shown.

6 is la pipe leadingI from the said container 5 and communicating with the pipe 4 at a point adjacent the burner 3, ass own. Pipe '4 is Vfurnished with a'hand-valve at 41, intermediate the container 5 and the point of connection at 61 between the pipes 6 and 4 and Vadjacent the .saidpoint of connection,- b

means of which hand-valve the iiow throug` :pipe 4 from the container 5 to theburner" 3 Inay be controlled as required. When handvalve 41 is o ened prior to' starting up, the gasolene is Iorced-through pipe 4 to the urner through the expansive power of c ompressed airwithin the upper portion of the container 5'. After starting up and when the power-pump, hereinafter referred to, is set motion the hand-valve 41 is closed again.

The pipe 6 has a similar hand-valve 62 adjacent the container, by means of which the lilow of gasolene from the container through the said pipe 'may be regulated.

7 designates a power-operated force-pump whichis combined with the pipe 6 for the pur ose of-forcing gasolene through the same to t e burner, the said pump being actuated from the engine in connection with which the burnerand boiler are employed in practice. In Fig: 2'said -engine is shown at 72 and the piston-rodthereof at 73. A pin 74,

connected withsaid piston-rod, works in the slot of a lever 76, the said lever being pivoted at 77. and being connected with the piston-rod 78 of said forceump. 8 is a handmeans `of which, when necessary, gasolene maybe forced through'the pipe 6 toward the Pipe 67 by IOC - 11 may be controlled. Iipe 16 leads from .tainer 15 and is accumulated in the latter.

`supply of gasolene which shall bel available ,pressed in said container until a sufficient' pressure is secured to insure proper feed of the gasolene to the pump, when required,

I through pipe 4.

13 is a pressure-gage employed in connection' with the pipe 1'2, and 14 is a three-way cock at the point of union of the pipes 1 1 and 12, by means of which the iiow of air through the said pipe may be controlled as hereinafter referred to. The gage 13 enables the degree of pressure within the container 5 to be ascertained. i

The purposes and mode of operation of the parts and connections thus far described are familiar and well understood.

In conformity with my invention I provide an auxiliarycontainer 15, also in communication with the pipe 11, the' said pipe 11 being extended in opposite branches from the point of connection 102 of the pipe 10 therewith, the respective branches leading to the container 5 and auxiliary container 15, respectively.

At 111 is a hand-operated valve with` which the pipe 11 is provided between the auxiliary container 15 and the point 102 of connection of the pipe 10 with said pipe 11, and by means of which hand-valve 111 communication between the air-pump 9 and the auxiliary container 15-v through the said` pipe the auxiliary container 15 and connects with the feed-pipe 6 at 161. In preparing for operation air is pumped into the container 5 until the required pressure is produced within thesame, the valve at 111 having been closed. Air then is pumped' into the saidl auxiliary container 15, the cock at 14 having been turned so as to disestablish connection between the pipe 11 and the container 5 through the pipe 12. The said cock, however, maintains connection between the pipe 11 and the indicator 13, so as to indicate the pressure which is secured within the auxiliary container 15.

During the regular working-of the engine and connected apparatus such portion of the volume of gasolene which is forced throu h the pipe 6 toward the burner 3 by the stroe of the pum 7 as is in excess of the rate of discharge t ough the burner finds its way through the pipe 16 into the auxiliary conthe auxiliary container 15 The purpose of store up under pressure a is to receive and for use in feeding the burner 3 at a time when the feed by means of the pump at 7 is arrested which communication through fuel which has entered the injury to or suspended for any reason .or by any cause whatever. Thus if during/ the running the Vmain system should become deranged or exhausted Vof its fuel-sup ly the required feed of gasolene would be rept up from the auxiliary container 15. In connection with the said auxiliary container 15 I provide means whereby after a predetermined pressure within the said container has been secured through the gradual forcing of the excess fuel-supply into the same relief is afforded by permitting the excess feed of gasolene to find its way back to the container 5. Thus with the pipe 16 I connect a pipe 17, leading to a needle-valve at 18 (shown in section in Fig. 3,) tlie latter being in communication through a pipe 19 withthe pipe-1.

In Fig-3 the couplingiwhich connects pipe 17 with the needle-valve is supposed to be indicated at 172. Iipe 17 is furnished with a hand-operated valve 171, by means of the said pipe with the needle-valve at 18 may be controlled, and the pipe 19 also isfurnished with a hand-operated valve at 191, by means of which communication with the pipe 4 through the needle-valve 18 and the pipe 19 may be controlled. l The needle-valve is of a self-acting variety intended normally to remain elosed,`so as to preclude the return 'of gasolene past the same to and through pipe 4 .to the container 5.-, It ordinarily remains vclosed during the regular action-of the apparatus. When, however, the predetermined pressure within the auxiliary container, 15 is attained in consequence of the gradual increase in the quantity of excess same, the needlevalve 18 opens, permitting How to take place past the same toward the container 5. Usually in practice the needle-valve' 18 IOO IOS

will have the needle 183,- Fig. 3, thereof con-f y nected with and operated by a diaphragm 184 of usual character,d the case for the said diaphragm being indicated at 181 and the continuationv of the 'said casing, which incloses the diaphragm-spring'185, being indicated at 182. If 'for any reason the phragm should ing to nieve the needle so as to open the needle-valve when the gasolene-pressure reaches the predetermined degree. In order to avoid the apparatus-as a result of such breakage vof the diaphragm, I providea bypass which is constituted by a pipe 20, vcommunicating with thespring-chamber 'of the portion V182 of the casing phragm and alsocommunicating with the pipe 19 below the seat of the needle-valve 18, with which the needle coacts.

In Fig. 3 the communication in the latter connection is through a small passage 201 in the body of the lower portion of theneedlevalve. When now' the diaphragmA breaks, the excess feed of gasolene finds its way through the diaphragm-casing andthe said IIO dla- Y break, there would be nothabove the diaby-pass pipe into the pipe 19 and through the latter and the pipe 4 back to the container 5.

'What I claim is- 1. In combination, theburner, the liquidflrel container, a pipe connecting said burner and container and through which the fuel flows under air-pressure, a second feed-pipe also communicating with the said container and burner, the power feed-pump whereby the fuel from said container is impelled Vthroughthe latter pipe to the burner, the auxiliary container connected with said second pipe and receiving a portion of the fuel which is fed-through the same, and means for forcing air into the respective containers to produce air-pressure in each thereof. 2.
